So i thought I would post an issue I resolved where my S4 began shutting off without warning. It would generally occur after playing on it for 5 or so minutes and I would notice my 3G/4G bars disappear just prior to it turning off. When I took my battery out I noticed it was not completely flat and slim like it should be, Instead it was slightly raised in the center. I ended up buying a high capacity battery (3900mAh) and it has solved my issue. Had it a month already and so far so good, battery life has also I proved significantly, hopefully this helps others with the same problem.
